The Escuela Tecnica de la Bicicleta has their own fixture for frame building. The fixture is set up based on a few critical dimensions, three of them are measured from reference surfaces on the fixture itself. BikeCAD version 20.0 features a new tab in the Fixturing dialog box where values for h, E, d, BB, and C are already pre-set to reflect the dimensions of this fixture. Dimensions A, B and D will be calculated and can be shown in the Jig setup tab of the dimensions dialog box.
